-LRB- CNN -RRB- -- The body of Venezuelan President Hugo Chavez will eventually be displayed publicly `` just like Lenin -LRB- and -RRB- Mao Zedong , '' the country 's vice president said Thursday on state-run TV .

`` The body of our leader will be embalmed , and it will ... be surrounded by crystal glass forever , present forever , and always with his people , '' Nicolas Maduro said .

Maduro will be sworn in as interim president in a special session of the National Assembly at 7 p.m. Friday , said National Assembly President Diosdado Cabello on Thursday on Venezuelan state broadcaster VTV .

The funeral for Chavez , who died at 58 Tuesday after a battle with cancer , will be held Friday in the capital , Caracas .

Maduro did not say when Chavez 's final resting place , at a military museum , will be ready . But people still will be able to view Chavez 's body -- lying in state in a wooden casket at a military academy in the capital -- for at least another week , he said .

`` Everybody can see him without any limits , '' Maduro said . `` We want anyone who wants to see him to have the chance to do so . ''

The South American nation is in a seven-day period of mourning , with schools closed for the week .
